Sorry mate. It's the third time you mention it and I still haven't answered.
The thing is I have no idea... I'm also not going to open one... I don't want to mess anything up. I can take a measurement if you want....

Installed the lights on my baby GS yesterday. Great product, the usual Givi standard. Came with everything: spots, brackets, harness, relay, fuses, switch, screws, and even covers for the screws. H3 lamps. Big, but very light. I aligned the spots to cover the dark area left by the low beam right in front of the bike (kinda like fog lights). I would like a little more dispersion from the spots (they are very focused).
